【Ingenious Design】The viscometer is equipped with 4 rotors for different viscosity scopes of samples. It features with premium lifting system and angle adjustment for less errores. You can adjust the knobs to get suitable height and position. 【Rotation Rate Of Rotors】 According to the viscosity range of different test liquids, different rotors (1,2,3,4) can be selected and different speeds (60,30,12,6) can be set. The knob adjustment is straightforward with a coefficient table on the top for easy reference. You can unlock a more unknown liquid viscosity. 【± 5% Accuracy】 The viscometer uses a measuring disc, and the viscosity values are measured by moving the rotor rotation through the spindle and spindle, has a large viscosity measurement range of 10-100,000 cps and the measurement error: ± 5%, give your determination enough to better control my processes. 【Motor Driven】The machine adopts a stepper motor driven by high subdivision, and the top of the machine is equipped with a standard horizontal air bubble, which has high sensitivity measurement and perfect data acquisition, so the test result is accurate and reliable. 【Application】 NDJ-1 is commonly used to determine and measure liquid viscosity in many applications such as grease, painting, plastics, pharmaceuticals, and adhesives. There are no restrictions on the liquid, just put the rotor in the liquid and test it. But the liquid you measure should NOT exceed 80 ℃.
